Third-party reviews

Based on ratings from across the web.
Reviews last updated: November 2026 · How we calculate this

What customers like about Soul Electronics Flex

  • Secure over-ear fit that stays in place during intense workouts
  • IPX5 waterproof rating makes them sweat and water-resistant
  • Energetic sound signature with deep, boosted bass suited for hip-hop and dance music
  • Lightweight design (approx. 18g) and includes a tangle-free cable
  • Good call quality with a microphone that effectively rejects background noise
  • Includes helpful accessories like a travel pouch and multiple ear tip sizes

What customers don't like about Soul Electronics Flex

  • The over-ear loops can be difficult to put on or remove quickly
  • Bass can occasionally be overpowering for genres like acoustic jazz or orchestral music
  • Some users report an 'odd' or inconsistent sound signature depending on the track
  • Microphone reliability issues reported by some long-term users
  • Over-ear hooks may not fit all ear shapes comfortably

Verdict

The Soul Electronics Flex is a set of wired, high-performance sport earbuds featuring an IPX5 water-resistant rating and a 3.5mm male connector. Designed for athletes, they utilize an over-the-ear rubber loop design and an antibacterial coating for a secure, hygienic fit during intense workouts. Key specifications include a frequency response of 20Hz–20kHz, 16-ohm impedance, and a lightweight 18-gram build that includes an in-line three-button controller for media and calls. Their main pros are a remarkably secure seal that survives heavy movement and sweat, alongside balanced sound quality. However, some users find the earloops can make the headphones difficult to put on or take off quickly, and the cable—while tangle-resistant—can occasionally snag without proper use of the included shirt clip.
